Narayana JTS standalone quickstart

Overview

An example of how to start and end JTS transactions. A JTS transaction requires an ORB.

Usage

Running Narayana JTS transaction

mvn clean compile exec:java  -Dexec.cleanupDaemonThreads=false -Dexec.mainClass=org.jboss.narayana.jta.quickstarts.TransactionExample

or

mvn clean compile
./run.[sh|bat]

Using the run script will run the example twice, once with JacOrb and then again but using JdkOrb.

Driving JTS transaction remotely with ORB API

There is also a second example that you must run manually using a bash script. The example shows how a client can connect to a remote transaction manager (TM) using a CORBA Name Service for looking up the TM. The example runs using either JacOrb or JdkOrb:

You need to set 2 environment variables to run the example:

JAVA_HOME: the location of the JDK

NARAYANA_HOME: the location of the narayana distribution (you can download it from the http://narayana.io/downloads/ while choosing the option 'Naryana Binary')

The script will also set:

HOST_ADDRESS: the IP of one of your network interfaces. Do not use the loopback connection (ie localhost or 127.0.0.1) please override the setting in start.sh if it is incorrect.

If you are running on Windows you will need to port the script to Windows batch commands.

Running with JacOrb:

  1. start a CORBA name server
./start.sh jacorb NS
  1. start a Transaction Recovery Manager
./start.sh jacorb RM
  1. start a JTS Transaction Manager
./start.sh jacorb TM
  1. start a transactional client program
./start.sh jacorb CL

Running with JdkORB:

as above but replace JacORB with JdkORB

Expected output

The run script will the example twice, the first run uses JacORB for the CORBA ORB followed by a second run using the ORB bundled with the standard JDK.

The orbd command is not bundled with JDK >= 11, see JEP 320 for more information. A quick way to get this quickstart running in the jacorb mode is to reuse the forementioned orbd bundled binary.

Install JDK 8, locate the orbd executable under the bin directory and create a symbolic link pointing to it, like so: sudo ln -s ${JDK_8_LOCATION}/bin/orbd /usr/bin/orbd. Tested with OpenJDK 11.

Both runs should produce a line indicating success:
